Patch by Kondapally Kalyan <kalyan.kondapally@intel.com> on 2013-03-27
Reviewed by Noam Rosenthal.

Covered by existing WebGL tests.

Source/WebCore:

This patch adds support to pass GraphicsSurface flags during it's client creation.
This would be helpful to determine cases when blending can be disabled on client
side i.e When AlphaSupport is disabled during Graphics Surface creation.
With GLX, we rely on Window to provide us with necessary information on client side.
This might not be the case on other platforms or when not using Window on X.
This patch doesn't change original behaviour of creating GraphicsSurface client
with default flags GraphicsSurface::SupportsTextureTarget and GraphicsSurface::SupportsSharing.
